Certain manufacturers have a mechanical key blade that can be used in an emergency to open the trunk or start the vehicle.

Battery Life

The majority of newer cars come with keyless entry and push button starting systems operated by a smart key fob, which uses proximity technology to connect with the car. These systems are powered by a tiny transmitter which is powered by a coin-sized lithium battery. Like any other battery that eventually requires replacement, this one too will need replacement.

The majority of smart key fob batteries last several years however this doesn't mean that they won't lose power and stop working quickly. If the fob is dead, it isn't able to unlock or start the car even when you hold it near the front door, and the key fob's light blinks.

These gadgets emit magnetic fields of their own which can interfere with and slow down the fob's transmitter.
